{x+y=1
{2x+3y=0


HELP ME !!!!!! URGENTE

Answer 1

X = 1-y

2x+3y=0

2(1-y)+3y=0

2-2y+3y=0

2+y=0

Y= - 2

X+y=1

X+(-2)=1

X-2 = 1

X = 1+2

X =3

(x, y) = (3,-2) ou x = 3 e y = -2

Answer 2

Resposta:

y=-2 e x=3

Explicação passo-a-passo:

x+y=1 •(-2)

2x+3y=0

-2x-2y=-2

2x+3y=0

y=-2

x+y=1

x-2=1

x=1+2

×=3
